The strategic rivalry between the United States and China has heightened since COVID-19. Secondary states face increasing difficulties maintaining a 'hedging' strategy between the United States and China. This Element introduces a preference-for-change model to explain the policy variations of states during the order transition. It suggests that policymakers will perceive a potential change in the international order through a cost–benefit prism. The interplays between the perceived costs and the perception of benefits from the order transition will shape states' policy choices among four strategic options: (1) hedging to bet on uncertainties; (2) bandwagoning with rising powers to support changes; (3) balancing against rising powers to resist changes; and (4) buck-passing to ignore changes. Four case studies (Australia, New Zealand, Singapore, and Thailand) are conducted to explore the policy choices of regional powers during the international order transition.
